sys/dev/sio sio.c
Log:
This problem has been in the serial driver for years, and I occassionally
see people trip over it. Do not set the FIFO trigger to just before it
would otherwise overflow. Give it a little more slop so characters aren't
lost if the interrupt is delayed by other system activities.
MFC maybe: 7 days
